WATERPROOFING MATERIAL PUMPING APPARATUS Martin Eisner, Oak Park, Mich.

Application June 12, 1956, Serial No. 590,994

1 Claim. (Cl. 137-267) cracks in masonry, concrete, brick or concrete block by following the crack through the wall to emerge on the inside of the basement wall, thus forming a complete closure against moisture and water.

Volclay includes an organic material having the ability to absorb twenty times its volume of water. After the absorbtion point is reached all additional moisture and water is repelled.

it is the object of the present apparatus to properly mix the Volclay with a permissible amount of water and pump and deliver the same under pressure through suitable conduits and pipes directly to the basement wall. This will provide a coating or seal which will rapidly dry and provide an effective water tight coating.

Volclay seals the outside and inside walls at the crack and also impregnates the outside soil adjacent the basement wall to a width of approximately 12 inches forming a zone of protection elfectively sealing ofi surface water. The Volclay is premixed in tanks, is pumped through a high pressure hose into spuds inserted in the ground at intervals of approximately two feet vertically with the first injection being made at footing levels. Subsequent injections directly through the ground are spaced above the first injection and with successive injections along horizontal rows until application is made over the entire wall up to the ground surface.

The mixture when once applied effectively seals basement walls and floors against seepage, dampness, sweating and surface water.

The Volclay mixture will not evaporate, wash ofi or deteriorate, and produces permanent waterproofing.

In the drawing:

Fig. 1 is a plan view of the present apparatus.

Fig. 2 is a fragmentary front elevational view thereof,

on an increased scale.

Fig. 3 is a fragmentary left side elevational view thereof on an increased scale.

It will be understood'that the above drawing illustrates merely one preferred form of the present apparatus and that other apparatus is contemplated within the scope of the claims hereafter set forth.

The present pumping unit for the above waterproofing material comprises platform 11 suitably mounted upon wheels 12. A pair of upright tanks 13 are mounted upon said platform and secured thereto; and are adapted to Patented June 3, 1958 r' CC 2 contain a fluid mixture of Volclay to be used for the underground waterproofing of basements, and particularly basement walls and floors. The tanks have outlet pipes 14 and 15 at their bottoms which extend through platform 11 and terminate in the pair of spaced parallel longitudinally and downwardly extending mixture supply pipes 17 and 17' with suitable'interconnecting elbows 16. Elbows 18 at the ends of pipes 17 and 17 connect opposite ends of transverse pipe 19.

Spaced shut-off valves 20 and 21 are positioned within pipe 19. A T fitting 22 .joins pipe 19 intermediate valves 20 and 21 and through pipe 23 joins the inlet of the preferably electric fluid motor pump 24.

Support 35 fragmentarily shown in Fig. 2 provides one means of suitably mounting and retaining the combination motor pump 24 directly below platform 11.

This construction provides a means of delivery of the water mixture of Volclay from tanks 13 to said pump,

which fiow may be cut off by the shut-01f valves 20 and 21.

Pump 24 has an outlet at 25 Figure 2 which joins the mixture delivery pipe 26 which has at its end as at 27 a quick change connection to permit the attachment there- 'to of a suitable connecting hose by which the Volclay Operation In operation two tanks are initially provided with a suitable quantity of Volclay, a water resistant expandible mineral containing such organic material as to have the ability to absorb approximately twenty times its volume of water.

With shut-off valves 20 and 21 closed and valves 33 and 34 opened, water under normal pressure from the city main enters through connection 28 and through pipe 29 and outlet pipe 30 delivering water to pipes 17 and 17' and upwardly through the outlet pipes 14 and 15 into tanks 13 for mixing with the Volclay therein.

Thereafter the water is turned off by closing shut-off valves 33 and 34. At the same time motor pump 24 is energized and valves 20 and 21 opened, permitting the flow of the water mixture of the Volclay through pipes 17 and 17' and pipe 19 into water pump 24 for delivery through outlet 25 and mixture delivery pipe 26 under a suitable predetermined pressure.

Having described my invention reference should now a motor pump having an inlet and having an outlet adapted for connection to a delivery hose, a T fitting pipe joined at one end to said transverse pipe intermediate said valves and at its other end to said pump inlet, a

water intake pipe mounted on and below said platform having an inlet adapted for connection to a source of -?5 water under pressure, an outlet pipe joined to said Water intake pipe adapted for connection at spaced points with end portions of said mixture supply pipes, at shut-off valve at each of said latter connections whereby water under pressure may be selectively supplied to each of said tanks from their bottoms, and a Waterproofing mixture may be alternately supplied to said pump on adjustment of said valves.
